Hey all,
First time poster here (garage thread is on the way ). I have owned a 1999 V5 WRX Wagon for about 4-5 months now. It has always had some issues when the engine got hot, after driving for long periods of time or just going hard, like the gears losing all smoothness when shifting and hearing an audible sound of the gear clomping in on take off, and what sounds like a thumping/banging noise when the wheel is anywhere near full lock, but now I believe the clutch has started slipping. I took it in for a service to the mechanic, and he put some sort of additive into the gearbox oil for what he saw as a possible solution to some of these issues, he did not fully clarify what exactly he put in though.
That night I went for a 80 or so km drive and after 30-40km in heavy Auckland outbound motorway traffic, unsurprisingly it started doing the stuff it normally does when it gets hot, except this time, if I floored it in 4th (and sometimes 5th) when it hit 4k rpm, it would jump to 4500rpm with no real increase in torque. I believe the clutch is slipping, though nowhere near as bad as some I have seen (only jumps about 500rpm). So I just wanted to clarify, does this seem like the clutch slipping? If so is it possible to salvage it instead of replacing the whole thing? If it does need replacing, anyone have any tips on how to go about it? And if anyone has any info on these other problems it would be greatly appreciated.
tl;dr: clutch seems like it is slipping 500rpm at 4k rpm in 4th, is new clutch necessary or is it salvageable?
Thanks
